Drought is the major stress limiting crop productivity and development in arid and semi-arid regions. Tomato genotypes have wide range of sensitivity to drought, two genotypes of tomato H-86 and EC-520061 were used in two different types of field experiment in 2016-2017 at Indian Institute of Vegetable Research, Varanasi. Each experiment was conducted in randomized complete block with three replications. Moisture level of one field was 80% and of another field was reduced to 40%. Several biochemical analyses consisting of various enzymatic and non-enzymatic antioxidant defense system and some factors of oxidative damage were analyzed in two experiment setups. The enzymatic activities Proline content, H2O2 and LPO increased in drought stressed condition of tomato plant at flowering stage of plant whereas Carotenoid content and MSI (Membrane Stability Index) decreased in both the genotypes. In drought tolerant genotypes enzymatic and non-enzymatic antioxidants were higher, whereas LPO and H2O2 content was low, but in case of drought susceptible genotype trend was reverse.
